I've been struggling to find ways to keep my 3 charged up during track days. Most local tracks I visit have 14-50 outlets available. Started with the original Gen II UMC, which adds about 10% per hour at 32 amps. Not enough to get me through four 20 minute sessions without supercharging. Recently bought a Gen I UMC, adds about 12.5% per hour at 40amps. Better, but still not enough.
Saw an idea posted in another thread to get a HPWC and attach a 14-50 plug to it and set it to 48 amps. This would give me about 15% per hour charge and may be enough to where I could do a full track day without having to leave to supercharge. I know it wouldn't meet code, but it also wouldn't be a permanent installation, and my understanding is a "continuous" load is one that runs for 3 hours or more. I doubt I'd be charging continuously for any more than 2 hours on a track day. On paper, 48 amps is less than 50, so seems like it would work. Would that hold true in practice as well, or is there a good chance I'd be tripping the breaker when I tried to use it?
